4 Conclusion

The Kamlan 55mm F1.2 can produce nice results with very small depth of field for portraits and for objects details but the sharpness is not good wide open and you need to close down to F2.8 to get good sharpness which defeat the main purpose of shooting with a F1.2 lens.

At 300 euros it could be a nice complement to a Zeiss 55 F1.8 , but at 500 euros better alternatives exist

Mitakon 50mm F0.95 : (750 eur) – manual lens , a bit more expensive but you get a real F0.95 very different from a F1.4 , sharper and with better contrast

Samyang 50mm F1.4 AF : (500 eur) very good lens very sharp with nice autofocus and depth of field close to the F1.2

Sony 50mm F1.8 : (300 eur) You don’t get the very small depth of field but at 300 euros everything else is better as from F2 on the Sony
